Description

The structure of floor sound insulation mat

The present invention relates to the structure of the sound-insulating floor mat, especially a sound-insulating mat structure that can prevent water and mud from penetrating into the sound-insulating layer, and can directly mix cement mortar on the surface to ensure convenient construction and good sound-insulating effect.

With the sound insulation regulations of the latest building law, the sound insulation effect between the floor slabs of the newly launched construction projects must be kept below a preset value (58 decibels), and the relevant construction companies must meet the above sound insulation requirements Generally, sound insulation pads with sound-absorbing and buffering effects are installed between the floors of buildings in order to achieve the preset noise reduction effect and meet the regulations.

Furthermore, due to the continuous increase of the height of various buildings, in order to save manpower and simplify the arrangement of hanging equipment, the construction methods of floor slabs and sound-insulating layer pads of each floor in the current buildings are mostly cement, sand and cement in one time. Materials such as sound-insulating mats are transported to each floor and stacked at each predetermined location; after the sound-insulating mats of the floor slab are fixed, cement and sand are mixed with water on site, and the mixed cement mortar Being superimposed on the sound-insulating layer mat, in addition to pressing and fixing the sound-insulating layer mat, it is also convenient for subsequent application of the upper surface finish (tile or floor tile).

In the new case of the Republic of China Patent Announcement No. M588054, a rubber fiber sound insulation pad (board) is disclosed, which is composed of a plurality of glass fibers, which are arranged in a staggered longitudinal interweaving manner and are needle-punched in a sheet-like shape with appropriate thickness and width. The carpet is soaked in a rubber solvent and then dried to shape; and the surface of the sound insulation pad (board) can be coated with a waterproof film to avoid water penetration.

However, in the above-mentioned structure, since its waterproof film system is directly coated on the surface of the sound-insulating pad (board), and most of the waterproof films have waterproof properties, they are soft and unable to withstand pressure and friction. The operation of mortar damages the waterproof membrane, so that water or cement mortar penetrates into the sound insulation layer pad, and reduces the shock absorption and sound insulation effect of the sound insulation layer pad after drying and hardening; therefore, the above-mentioned operation of mixing cement mortar cannot be directly applied on the sound insulation layer pad However, it must be carried out at other reserved sites, and then the mixed cement mortar is transported to the construction site and stacked on the sound insulation layer pad, which often causes inconvenience in construction, and the last construction of the same floor in the building room or site, you may need to wait for the cement mortar in other rooms or sites to dry before mixing the cement mortar, or mix the cement mortar on other floors and then transport it to the last room or site for construction, which will seriously affect the construction efficiency.

In the new case of the Republic of China Patent Announcement No. M613139, a sound-insulating layer structure of a floor slab is disclosed, which is a sound-insulating middle material covered by two-sided substrates, and a waterproof layer is provided between the surface substrate and the sound-insulating middle material The waterproof layer is made of environmentally friendly polyolefin, the surface substrate is polyester cotton or porous fiber cloth, and the capillary fibers on the surface can be directly adhered to the mixed soil, and the sound insulation material is porous fiber material or polyolefin foam (IXPE; EVA), which has pores and produces a noise-reducing effect.

Although the above-mentioned structure can use the five-layer superimposed structure to achieve the preset sound insulation and noise reduction and be easy to combine with the mixed soil, the five-layer superimposed structure not only greatly increases the production cost, but also causes The overall thickness increases, which affects the design of the floor thickness, which is not conducive to the utilization of indoor space.

In view of the above-mentioned shortcomings in the actual application of the common floor sound-insulating layer mat structure, the inventor studies an improvement method for these shortcomings, and finally the present invention is produced.

The main purpose of the present invention is to provide a structure of floor sound-insulating layer cushion, which is to arrange a filter layer capable of blocking water slurry on one surface side of a sound-insulation layer made of polyester fiber material, and further combine on the filter layer A strong and elastic interface layer, and the interface layer has the characteristics of being easy to combine with the filter layer and cement mortar (or cement mortar), and a shielding protection mechanism can be formed for the filter layer by using the interface layer , so that the filter layer can avoid abrasion and damage during the construction process, and the filter layer can effectively prevent water or cement mortar from penetrating into the sound insulation layer, so as to avoid hardening and deterioration and blockage of the internal fibers, so that the sound insulation layer can maintain a normal state Sound insulation and noise reduction effect.

Another object of the present invention is to provide a structure of floor sound-insulating layer pad, which is suitable for directly mixing cement mortar and mortar on the interface layer because the interface layer can provide a shielding protection mechanism on the filter layer. The operation of superimposing cement mortar can simplify the construction procedures on site, so as to achieve the effects of improving overall construction efficiency and reducing production costs; and the interface layer has good bonding with the cement mortar (or cement mortar) at the same time, which can After the cement mortar dries, it is firmly combined with the sound insulation layer pad to effectively ensure the overall construction quality.
